extracted from <a href=\"https:\/\/en.wikipedia.org\/wiki\/Leonardite\">leonardite<\/a>, a young oxidized lignite rich in <a href=\"https:\/\/en.wikipedia.org\/wiki\/Humic_acid\">humic acid<\/a>. It is used worldwide as a fertilizer raw material and plant biostimulant.<\/p>\n<p><strong>Micro Granule I<\/strong> is the spray-dried grade of our mineral-source potassium fulvate, and it does one thing better than anything else we make: <strong>it dissolves almost instantly<\/strong>. Drop it into water and it goes in like instant coffee \u2014 no waiting, no stirring, no residue.<\/p>\n<p>The secret is the structure. Spray drying produces a <strong>hollow micro granule<\/strong> with a very high surface-area-to-mass ratio and a porous wall. Water penetrates from outside and inside at once, so the granule collapses into solution in seconds rather than minutes. You also get the two handling benefits that come with a granule rather than a powder: <strong>zero dust<\/strong> and <strong>excellent flow<\/strong>.<\/p>\n<p>At <strong>50% fulvic acid<\/strong> and <strong>10% K\u2082O<\/strong> minimum it is a step lower in fulvic than the powder and flake grades \u2014 that is the honest trade-off for the instant-dissolve structure. For premium water-soluble fertilizers, soluble retail packs, hydroponics and any application where the operator will not wait around, this is the grade that removes friction.<\/p>\n<\/div>\n<div class=\"jf-sec\" id=\"benefits\">\n<style>.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits[data-kb-block=\"kb-adv-headingkb-h2-benefits\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits[data-kb-block=\"kb-adv-headingkb-h2-benefits\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits[data-kb-block=\"kb-adv-headingkb-h2-benefits\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h2>Key Benefits<\/h2>\n<div class=\"jf-grid\">\n<div class=\"jf-card\">\n<h4>Dissolves in seconds<\/h4>\n<p>Hollow spray-dried structure means water attacks the granule from both surfaces.

You trade roughly 5 percentage points of fulvic acid for instant dissolution and zero dust. If maximum fulvic content per tonne is your priority and you have agitation available, choose Powder I or Flakes I.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Does it really need no agitation?<\/summary>\n<p>Correct \u2014 a brief hand stir is enough. That is the whole point of the hollow structure. It is the only grade in the Type I family we recommend for systems with no mechanical mixer.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Does it absorb moisture faster than the other grades?<\/summary>\n<p>Yes, and this is the one thing to watch. The porous granule takes up atmospheric moisture readily. Keep bags sealed, use opened bags promptly, and store in a dry place. In humid climates we recommend the foil-lined packaging.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Is it suitable for organic certification?<\/summary>\n<p>Our fulvic acid line holds CERES organic certification to NOP standard. Send us your target market and programme and we will attach the applicable current certificate.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>What is the minimum order and lead time?<\/summary>\n<p>Made-to-order on a spray drying campaign. MOQ is higher than the stocked powder and flake grades \u2014 tell us your volume and we will quote a firm MOQ and lead time, typically 15\u201325 days.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Do you supply a COA per batch?<\/summary>\n<p>Yes. Micro Granule I ships with a full COA including the complete heavy metal panel (Pb, As, Hg, Cd) tested to GB 18877-2009.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Can it be blended with granular NPK?<\/summary>\n<p>It can, and its uniform 2\u20133 mm size resists segregation well. But note the storage caveat: once blended into a hygroscopic bulk blend, use the blend promptly rather than warehousing it.<\/p>\n<\/details>\n<\/div>\n<\/div>\n<div class=\"jf-sec\"
